可以.這個(gè)句子沒問題.
使用非限制性定語從句修飾整個(gè)句子時(shí),要注意區(qū)分用as還是which.由as,which 引導(dǎo)的非限定性定語從句,as和which可代表整個(gè)主句,區(qū)別主要有兩點(diǎn)：
(1） as 引導(dǎo)的定語從句可置于句首或句中,而which引導(dǎo)的從句只能放在句尾.
(2） as 代表前面的整個(gè)主句并常在從句中作賓語或被動(dòng)句的主語,而which常在從句中作主語.
（3）當(dāng)主句和從句語義一致時(shí),用as；當(dāng)主句和從句語義轉(zhuǎn)折不一致時(shí),用which.比較并體會(huì)一下：
He made along speech,as we expected.
He made along speech,which was unexpected.
